The hazard assessment should begin with the identification of what natural hazards can be expected and how they might change in the short and medium term as a result of climate change. First of all, all of the potential hazards are identified. Then the areas that could be affected by the hazard are marked, this is called Hazard Mapping. The magnitude, intensity and frequency of the hazards are determined and the causes of the hazards are investigated. Hazards could include earthquakes, volcanic eruptions, floods, drought, cyclones and epidemics.
